# @GenericError: this is used for errors that don't require a specific error
#                class. This should be the default case for most errors
#
# @CommandNotFound: the requested command has not been found
#
# @DeviceEncrypted: the requested operation can't be fulfilled because the
#                   selected device is encrypted

# @DeviceNotActive: a device has failed to be become active
#
# @DeviceNotFound: the requested device has not been found

# LostTickPolicy:
#
# Policy for handling lost ticks in timer devices.
#
# @discard: throw away the missed tick(s) and continue with future injection
#           normally.  Guest time may be delayed, unless the OS has explicit
#           handling of lost ticks
#
# @delay: continue to deliver ticks at the normal rate.  Guest time will be
#         delayed due to the late tick
#
# @merge: merge the missed tick(s) into one tick and inject.  Guest time
#         may be delayed, depending on how the OS reacts to the merging
#         of ticks
#
# @slew: deliver ticks at a higher rate to catch up with the missed tick. The
#        guest time should not be delayed once catchup is complete.

# BiosAtaTranslation:
#
# Policy that BIOS should use to interpret cylinder/head/sector
# addresses.  Note that Bochs BIOS and SeaBIOS will not actually
# translate logical CHS to physical; instead, they will use logical
# block addressing.
#
# @auto: If cylinder/heads/sizes are passed, choose between none and LBA
#        depending on the size of the disk.  If they are not passed,
#        choose none if QEMU can guess that the disk had 16 or fewer
#        heads, large if QEMU can guess that the disk had 131072 or
#        fewer tracks across all heads (i.e. cylinders*heads<131072),
#        otherwise LBA.
#
# @none: The physical disk geometry is equal to the logical geometry.
#
# @lba: Assume 63 sectors per track and one of 16, 32, 64, 128 or 255
#       heads (if fewer than 255 are enough to cover the whole disk
#       with 1024 cylinders/head).  The number of cylinders/head is
#       then computed based on the number of sectors and heads.
#
# @large: The number of cylinders per head is scaled down to 1024
#         by correspondingly scaling up the number of heads.
#
# @rechs: Same as @large, but first convert a 16-head geometry to
#         15-head, by proportionally scaling up the number of
#         cylinders/head.

# @path: The path within the object model.  There are two forms of supported

#
#        Absolute paths are derived from the root object and can follow child<>
#        or link<> properties.  Since they can follow link<> properties, they
#        can be arbitrarily long.  Absolute paths look like absolute filenames
#        and are prefixed  with a leading slash.
#
#        Partial paths look like relative filenames.  They do not begin
#        with a prefix.  The matching rules for partial paths are subtle but
#        designed to make specifying objects easy.  At each level of the
#        composition tree, the partial path is matched as an absolute path.
#        The first match is not returned.  At least two matches are searched
#        for.  A successful result is only returned if only one match is
#        found.  If more than one match is found, a flag is return to
#        indicate that the match was ambiguous.
#
# @property: The property name to read

# Returns: The property value.  The type depends on the property type.  legacy<>

# @dump-guest-memory
#
# Dump guest's memory to vmcore. It is a synchronous operation that can take
# very long depending on the amount of guest memory. This command is only
# supported on i386 and x86_64.
#
# @paging: if true, do paging to get guest's memory mapping. This allows
#          using gdb to process the core file.
#
#          IMPORTANT: this option can make QEMU allocate several gigabytes
#                     of RAM. This can happen for a large guest, or a
#                     malicious guest pretending to be large.
#
#          Also, paging=true has the following limitations:
#
#             1. The guest may be in a catastrophic state or can have corrupted
#                memory, which cannot be trusted
#             2. The guest can be in real-mode even if paging is enabled. For
#                example, the guest uses ACPI to sleep, and ACPI sleep state
#                goes in real-mode
#
# @protocol: the filename or file descriptor of the vmcore. The supported
#            protocols are:
#
#            1. file: the protocol starts with "file:", and the following
#               string is the file's path.
#            2. fd: the protocol starts with "fd:", and the following string
#               is the fd's name.
#
# @begin: #optional if specified, the starting physical address.

#          and @length
#
# @format: #optional if specified, the format of guest memory dump. But non-elf
